Wow, almost 13k people in the telegram. This is really a high-level project, it is likely that they will collect hardcards for the day, and it is quite possible that in a few minutes. I wanted to join private sale, but 150 ETH is too much for me.
You still can join on public sale which only need 0.1 ETH as minimum investment and max 50 ETH or with CMT token.
I believe you will not be able to participate with 0.1 ETH public sale.
Arcblock is a project of high interest, so the amount of participants is very large, you can see 13k people in the telegram and they have full whitelist
